Think about the scene in Fight Club where the homework is to go out and start a fight. It isn’t easy. Most people have never hit another person their entire lives.

If it wasn’t, people would be fighting in parking lots everywhere you go.
The inertia of most peoples lives is to avoid conflict. This is why only a handful of people in any building you happen to be standing in are suited to leadership roles.
Now, if you can get one of those guys in the right conditions to stir up a mob hive mind then the game changes. Until then, most people will be propelled forward by inertia and conflict avoidance.
